UCI Bans Front Jersey Pockets and Limits Bike Computer Size

The UCI is implementing new regulations to limit bike computer sizes and ban front jersey pockets to improve rider safety and sporting fairness. According to the governing body, bike computers will be capped at 126 x 71mm by January 2028, and jersey pockets must be moved exclusively to the rear by July 1.

Why is the UCI limiting bike computer sizes?

The UCI decided to update rules on on-board technologies to reduce the “cognitive load” on riders. According to the governing body, studies show that too much data during a race can increase workload, which is a key factor in accidents.

The new maximum dimensions for bike computers are 126 x 71mm. This limit aligns with the largest products currently on the market, such as the Wahoo Ace, which measures 125 x 70mm.

While some argue larger screens prevent riders from straining to see data, the UCI believes limiting size prevents an excessive increase in data that could compromise safety. This ban takes effect in January 2028.

Did You Know? The UCI has a history of strict equipment enforcement, recently ejecting a leading competitor from the Giro d’Italia Women over a contested 20g weight violation.

How do the new jersey pocket rules work?

Starting July 1, jersey pockets must be located exclusively on the rear of the garment. The UCI is cracking down on front internal pockets, which some riders used for nutritional products or hydration bladders, as seen in the recent Unbound Gravel.

The governing body noted that these front pockets alter a rider’s body shape. According to the UCI, studies demonstrate an aerodynamic advantage from this practice, which raises issues of sporting fairness and increases the severity of accidents due to higher speeds.

There is one specific exception. A front pocket is still permitted if it is intended solely to hold a radio communication device.

Expert Insight: Samantha Carter notes that these rules highlight a growing tension between aero-optimization and safety. By removing “kangaroo-style” pockets, the UCI is prioritizing a standardized body profile over the marginal gains riders seek through modified apparel.

What other equipment has the UCI regulated?

These latest moves follow a series of strict mandates. The UCI has already imposed limits on handlebar width, sock heights, and rules regarding peeing during races.

New UCI Bike Computer Rules: BIG is BANNED!

The governing body continues to scrutinize how technology and fashion impact the sport. Whether the motivation is retro style or aerodynamic ambition, the UCI is moving toward a more traditional jersey silhouette.

What may happen next for cycling technology?

The UCI Management Committee has suggested that more research is needed. They may engage with stakeholders to better understand how riders interact with various data streams during competition.

Given the focus on cognitive load, it is possible that further restrictions on the types of data displayed on screens could be explored. Future updates may also address other aerodynamic modifications as new studies emerge.

Frequently Asked Questions

When do the bike computer size limits take effect?
The ban on bike computers exceeding 126 x 71mm will be in place by January 2028.

Are any front pockets allowed on jerseys?
Yes, but only a pocket intended solely for a radio communication device is permitted starting July 1.

Why did the UCI ban front internal pockets?
The UCI found that these pockets alter body shape for an aerodynamic advantage, which they believe impacts sporting fairness and increases accident severity due to increased speed.

Do you think limiting the amount of data riders see will actually make racing safer?
